If you will not be attending, you can give or sell your ticket to another person without the need to request a name change, you only need to send that person your PDF file and with that he/she will be able to access. Remember that once you have sent it, you will no longer be able to use it because the other person will enter with the QR and in access control only 1 ticket can be valid. Do not share the photo of your ticket on social networks, as there may be a misuse of your information.
